To provide an inexpensive product by manufacturing a rotatable connecting equipment in sealed structure in simple constitution.

This connecting equipment connects a wound body pipe 8 and a force feeding pipe 2 in a pump device furnished with a rotation axis 4 to rotate by external force from a power source, the wound body pipe 8 wound in a ring shape on an outer periphery with the rotation axis 4 as its center and the force feeding pipe 2 connected to the wound body pipe 8 and to discharge gas and liquid flown in from one end of the pipe 8 by rotation of the pipe 8 and raised in pressure to each other, a cylindrical member 1 which is a first connecting member one side of which is connected to the force feeding pipe 2 and a cylindrical rotating member 3 which is a second connecting member one side of which is connected to the cylindrical member 1 free to rotate and in a sealed state and the other end of which is connected to the wound body pipe 8 are provided and flow passages 1e, 3a to pass the gas and the liquid are formed on the cylindrical member 1 and the cylindrical rotating member 3.
